1" b all whom it may concern: I

Be it known that I, ROY E. HIGBEE, a c1t1- zen of the United States, and a resident of Windsor, in the county of Henry and State of Missouri, have made an Improved Device for use in Wiping Pipe-Joints, of which the following is a specification.

My invention is an improved device for holding a nipple or ferrule in due position on the end of a lead pipe while the oint is being wiped.

The details of construction, arrangement, and operation of the device are as herelnafter described and illustrated in the accompanying drawing, in which Figure l is a perspective View of the complete device. Fig. 2 is a longitudlnal section of a portion of the same. Fig. 3 is a perblock or so-called head adapted to slide on a rod which forms a prominent member of the device. Figfl 1s a horizontal section on the line 4.-4 of Fig. 1.

A indicates a sleeve whose closed outer end is conical, and it is provided interlorly with a threaded socket into which a rod G is screwed. The lower end of said rod is also screw-threaded for engagement with a nut I, which is provided with lateral dovetail notches to engage jaws H. The upper ends of the jaws are pivoted on pins D in the ears of a block D, hereinafter termed the head, which is adapted to slide on the rod G. The lower portions of the jaws H are curved slightly to better adapt them for insertion in the lead pipe, and they are toothed externally, as indicated at H. A nipple-em gaging device B is mounted on the upper portion of the rod G, above a polygonal stop collar G, and the same comprises a cylinder having a solid bottom and open at its upper lateral flanges or end and provided with their wings which are of triangular shape,

widest ends being upward so that the device is in efl'ect conical and thus adapted to enter the mouths of nipples of different diameters.

, The sleeve A before referred to is slidable in the cylindrical body of the device B. A spiral spring surrounds the rod within the sleeve and member B, and its ends bear against the outer ends of the ferrule A and nipple member B, thus pressing them in opposite directions.

The manner of using the device will now be understood. It being assumed that a soldering nipple or ferrule has been applied to the end of a lead pipe, the jaws H are dropped into the nipple and pipe until the flanges of the member B enter the mouth of the nipple and bear laterally against the upper portion of the same. It is apparentthat the shape of the flanges or wings of this de vice will cause it to slide down to place in nipples of difierent diameters. T he toothed portions H of the jaws H, upon sliding down on the spreading device I, will be forced outward into engagement with the interior of the pipe, and upon rotating the sleeve A the rod G will be acted upon in such manner as to spread the jaws more or less so as to grip the pipe firmly at the same time that the conical member B is drawn down upon the nipple to a corresponding degree. It is apparent that by pressingon the sleeve A more or'less, the spring I will be compressed correspondingly, and the flanged nipple-holding device I will therefore press on the nipple and hold it firmly in place while solder is being applied to the joint. To release the'device after the joint has been wiped, it and the pipe in which it is inserted are turned up side down and the sleeve A is pressed on the floor, thus again compressing the spring J, which pushes rod Gr upward and carries the spreading nut I with it, thereby removing the teeth H of the jaws H from their hold on the lead pipe, whereupon the weight of the jaws and the head D will cause them to slide down on the rod G until the head D comes in contact with the stop collar of the rod G, so that the entire device falls out free of the lead pipe and the nipple.

What I claim is:

.1. The improved device for the purpose specified, comprising a member adapted to bear upon the sliding nipple; a screw rod; a stop collar on said rod and an adjustable sleeve screwed on the upper end of the rod; a spring bearing in opposite directions against said member and sleeve; jaws pivotally connected and slidable on the said rod, the same being adapted to enter the pipe and grip the same internally; and a spreader applied to the lower portions of said jaws, as described.

2. The improved device comprising a conical member adapted to enter and bear upon a nipple; a screw rod having a stop collar and on which said member is adapted to slide; an adjustable sleeve screwed on the rod, and thus adapted for longitudinal adjustment thereon; a spring acting on the its adjustment, as described.

adapted to be inserted in'a pipe and to grip the same interiorly; and a, device applied to the lower portion of the rod and serving to.

spread the jaws more or less according to 3. In a device for the purpose specified, the combination, With jaws for gripping a lead pipe interiorly, ofarod provided with a stop collar, and onlwhich said jaws, are

slidably adjustable; a conical memberQWhich is slida'bleon the upper portion of the rod above the stop collar and having lateral-tridiameters'ya sleevewhich isslidable on said member and closed at its outer end, and

screwed uponiv the aforesaid rod; and a spring interposed vbetween such sleeve and the flanged member; as described.
